a guy who you will always love to be around because of his rocking personality but occasionally you turn to him when you crave a hookup. You will always love him but the circumstances do not allow you to have a true relationship so you treasure the intimate times you share but know you cannot get fully attached. This is often the case with couples who break up..

" You're my part-time lover and a full time friend" from the song by the moldy peaches.. featured in the movie Juno :)
-my ex boyfriend Max is my part-time lover and my full time friend. He's such as sweet guy and a the best romantic partner but he lives to far away to be my man.
